According to the report, the revenue of mobile application worldwide will be 188 billion USD by 2020. More than 2.8 million mobile apps are available on the Google Play Store and 2.2 million applications on Apple App Store. People have downloaded more than 180 billion-times applications from the Apple App Store so far, and it increasing continuously. Hence, it is important that the QA testers should test the apps thoroughly with real-time scenarios.
Interrupt testing is a part of mobile app testing where the mobile app will be interrupted abruptly with various scenarios. The businesses or developers perform it to verify how the mobile application reacts to the interruption. It ensures that the application runs in the background during the interruption and resume successfully then after.
Important Scenarios of Interrupt Testing
- Phone Call When the Mobile Application Is Running: This scenario is to check how the application resuming its state when a mobile got the voice calls. It should start again its state without any hassle.
- Abruptly Removes Battery: When the battery is removed while the app is running, it should restart, or it should be paused based on its functionality.
- Low Battery or Full Battery: Run the mobile application in low battery condition and check its performance. Also, check the application performance when the battery is full. In both the conditions, the performance should not vary. When the app is running, if the battery is low or it becomes full, the system should display as usual.
- Connect Charger: Run the application when the mobile is charging or connects the charger when the app is running. In both cases, monitor the application performance and check the display of the charger symbol.
- OS Upgrade: Upgrade the Mobile OS and check how the application is running with the higher version of OS. Also, check its memory consumption after the OS upgrade.
- Device Shutdown: Monitor the application behavior when you shut down the device or restart the device.
- Connect to the Wi-Fi router: Connect the Wi-Fi or change the mobile internet from network to Wi-Fi when the app is running. This change should not affect the mobile application in any way. Also, the Wi-Fi connection symbol should not be disturbed.
- Kill the App by Using Any Other Tools: By using any other tools, try to kill the mobile app and check the restart process of the application. Also, the application should indicate the third-party tool which killed.
- Incoming Messages and MMS: Monitor the app, if it shows the alerts properly when the message comes. And also try to read the incoming messages when the app is running.
- Remove and Insert Data Cable: When the app is running, remove the data cable and check the app progress. Also, insert data cable when the app is running. Monitor the App progress is both the cases.
- No Network Coverage: When you run the web application in no network or weak network coverage, the application should display the proper error message and if the device moved to network coverage, this application should resume properly.
- Uninstall and Check the App: Uninstall and check, if the app is creating any file or any problem with the device.
- Run the App in Low Memory: When the mobile memory is low, run the application and monitor its progress. If the memory is low to run the application, it should show error properly. For example, if you are trying to take a picture using the mobile camera, if the memory is low, it shows the memory full error message.
Tools To-Do Interrupt Testing
Various testing tools are available to automate the interrupt in a mobile application. Some of the important tools for Android and IOS are:
- Mautomate: This automation tool is used to record the mobile testing.
- Wizard Tool: With this tool, the developer can create interruptions when the app is running.
- UIAutoMonkey: It’s a script to perform stress test and interrupt testing for the mobile application by generating multiple commands for that application.
- Monkey Tools: It’s a command line tool to automate mobile testing by running in any emulator instance.
Challenges in Interrupt Testing
- Too Many Networks: When developer or tester wants to interrupt, the application running by invoking the external call, there are many network scenarios to cover the testing.
- Many OS Available: The app requires testing on many OS like Android, iOS, Windows, etc. Moreover, the developers or testers need to test the application on other devices like tab or iPad.
- Difficulties in Replication: When a call or message interrupts the mobile application, developer or tester requires the real network phone number. Many times, they need to go to a particular location if the mob app function depends on the location.
Clearly, interrupt testing is the significant part of mobile testing. It takes the accountability that the mobile application should work properly with any interruption, and it can restart and resume according to the commands from the device.
